“These effects of ubiquinol are independent of those of exogenous antioxidants, such as vitamin E, although ubiquinol can also potentiate the effect of vitamin E by regenerating it from its oxidized form.”
“The tocopherol mediated propagation was observed notably at low rate of radical flux, but this was suppressed by reductant such as ascorbic acid and ubiquinol.”
“In the regeneration reaction of alpha-tocopherol , deuteration of ubiquinol increased and decreased the activation energy and the second-order rate constant by 6.1 kJ/mol and a factor of 18.3, respectively.”
“In vitro experiments demonstrated that reduced UQ ubiquinol ) can improve the chain‐breaking activities ofα‐tocopherol by recycling the antioxidant‐derived reaction product, the chromanoxyl radical, to the native antioxidant.”
